Danieli to supply H3 rolling mills to Russian steelmakers Abinsk Electric Steel Works Ltd (AEMZ) and Novorossiysk Rolling Plant LLC (NPZ) have both ordered H3 wire rod lines from Italian plant builder Danieli. AEMZ has ordered a new 600kt/yr H3 wire rod line to be installed at its plant in Abinsk, in Russia’s Krasnodar region. NPZ’s equipment will have a 500kt/yr capacity and is destined for installation at Novorossiysk, also in the Krasnodar region. According to Danieli, AEMZ’s equipment will be used to produce wire rod coils (5.5to 16-mm-diameter smooth rounds; 6- to 12-mm-diameter quenched and microalloyed rebar) for construction purposes, welding wire and CHQ grades. NPZ’s equipment will roll 150x150 billets into 5.5 to 16-mm-diameter wire rod and deformed wire rod in coils weighing up to 2.1 tons. Danieli H3 mills are claimed to operate at over 100 metres per second. They incorporate an ESS energy saving system, cantilever-type and SHS housing-less stands and fast-finishing blocks. Danieli’s structure control system includes a water-cooling line suitable for wire rod quenching and controlled cooling, while an oil-film
bearing loop-laying head, rotary reforming tube and easy-down system are claimed to guarantee the perfect coil pattern. Danieli H3 mills are typically supplied alongside Danieli Centro Combustion reheating furnaces equipped with the latest-generation, ultra-low

German steelmaker Georgsmarienhütte (GMH) has successfully commissioned a KOCKS 4D EAGLE full profile measurement gauge; Kocks claims it is the most advanced laser light sectioning method currently on the market. The Kocks system replaces an existing light measurement gauge and is installed at the exit of GMH’s existing KOCKS RSB 370/6. It covers a production diameter range from 19.5 mm to 82.3 mm. The figure 6 means the RSB 370 has six stands, and the figure 370 is the size of the roll diameter. RSB stands for reducing and sizing block (for bar and wire rod). “The KOCKS 4D EAGLE is a profile measuring gauge. It measures the profile of the bar and gives information back to our SCS – size control system. Thanks to the high measuring frequency in combination with sophisticated software algorithms, the 4D EAGLE realises counter measures in the shortest possible time. This greatly assists operators in immediately identifying anomalies in the rolled product, thus helping to increase mill profitability and, therefore, it improves process transparency,” a KOCKS spokesperson explained. “The KOCKS SCS is a real-time closed-loop control system to optimise the operating parameters for a 3-roll reducing and sizing block in order to achieve and maintain the optimum operating state for the tightest tolerances,” the spokesperson said, adding that, in combination with the 4D Eagle, improves product quality.
